7 identical to the retainingmea nsiembodiediin my application, book holder, Serial No. 371,274 filed June 15, 1929. Consequently, a brief description of the retaining means is thought to sufiice. This means comprises two sets of prongs 27 and 28, the former being fixedly associated with the back section 21, while the latter is removable to facilitate the insertion and removal of a book to and from the frame. adapted to be projected between the leaves of the book and when the prongs 28 are'secured in fixed position, the book is securely attached to the back section. 7 As best illustrated in Figs. 3 and/l, the book holding frame is adapted to be supportedln "elevated positionby means of a bracket including a pair of channeled links 29 and 30, 'hingedly connected to each other and to the back section 21'and the angle bar 22. As shown inFig. 2, a spring 31 is connected to the links 29 and 30 so that when they are moved to-extended position, the spring-acts to maintainthem in such position, but once the links are folded, the spring acts reversely g5 and to maintain the links in folded position. By the provision of a lever '32 pivotedon the back section 21, the upper link 30 can be moved upwardly to break the joint between the linksso that the bracket can be moved to $0 folded position and the book holding frame moved to lowered position. This lever 32 is provided with an extension 33which is'engaged by a leaf spring 3 1 secured to the back section and operating to urge the lever up- 35 wardly so that it tends to actuate the upper link to collapse the bracket. 'A cam 35 is' 'secured'to theside section so that when suchsection is moved to open position the cam will engage the extension 33 and force 4 the lever 32 downwardly against the actionof 'the spring 34, in consequence of which the lever is prevented from acting to collapse the bracket. V 1

From the foregoing construction, it will be '45 manifest that the lever 32-normally acts to collapse the bracket formed by the links 29 and 30, but that in the open position of the side section 25, the cam functions to render the, lever 32 inactive, so that once the bracket is moved to extended position it will maintain such position underthe action of-the spring 31. Conversely, when the side section 25 is moved to closed position, the cam disengages the extension 33 so that'the spring 34. isfree to actuate the lever 32 to collapse the bracket andthus' permitlowering of the frame to its normal position. The frame in its movement to lowered position, is guided by an arm 36 secured to the angle bar 22, and lathe side sections 24 and 25 of the frame to- *gether with the book contained thereinare urged in the direction of the arm 36 by means of a leaf spring 37 secured to the outer side of the side section 25. This spring 37 has us sliding contact with the plate 17. 1 However,

frame reaches lowered position, the frame These prongs 27 and 28 arev the primary purpose of the arm 36 is to engage, move, and hold the side section 24 in closed position as the book holding frame is moved to lowered position, so that once the 0 will be retained in closed position at one 7 side of the desk. The lowermost position of the frame is defined by means of a yoke 38 secured to the angle bar 22 and engaging the back section 21. This yoke 38 may be constructed of spring steel so as to cushion the frame in its movement to lowered position "and to thereby prevent injury to any of its parts. a V

7 In the operation of the book holder, it normally occupiesthe loweredposition shown in Figs. 1 and 3, and in which position the frame is closed to embrace and hold a book in closed position at one side of the desk. When desiring to gain access to the book, the-holding frame is lifted to elevated position-in which the side sections 24 and 25 are free to swing to open position, it beingunderstood that in moving the frame to elevated position, the side sections are extended beyond the confines of the plate 17 and the arm .36. As. previously explained, movement of the side section 25' to open position actuates the cam 35 to preventthe lever 32 from actuatin the upper link 30. so that the foldable brac et is maintained in extended position and thus the frame is held in elevated position. In the open position of the frame, any page, of the book may be referred to, the side section 25 being extended over the top of the desk to support one-half of the book, and the other side section '24 extendingto one side of the desk and supporting the other half of the book." Thus, the book is supported in convenient position for'reading.

3 To return thezbook'to normal position at the side of the desk, it is only necessary to close the frame as then the cam 35 functions tocollapse the links 28'and 29, whereby, the

frame may be lowered vertically at one side of the desk and retained in closed position. Although I have herein shown and de scribed only one formof book holder embodying my invention, it is to be understood that various changes and modifications may 1 be made herein without departing from the spirit of the invention and the spirit and scope of the appended claims.

2. A book holder, comprising a plate adapted to be secured to a vertical support, an angle bar secured to the plate, a book holding frame including a back section hingedly mounted on the angle bar, a pin and slot also connecting the back section and angle bar, means on the bracket tending to maintain the latter extended when moved to extended position, a lever on the back Section operable to collapse the bracket against the action of said means, a spring on the back section tending to actuate the lever to collapse the bracket, and a cam on one of the side sections operable by movement of the side section to open position to move the lever to a position in which it is ineffective to collapse the bracket.

3. A book holder as embodied in claim 2 wherein one of the side sections is provided with a spring positioned to have wiping contact with said plate when the frame is moved downwardly for holding the side section in closed positon, and an arm on the angle bar to engage the other side section for holding the latter in closed position.

t. A book holder, comprising a support, a book holding frame including a back section hingedly mounted on the support and side sections hingedly connected to the back section to occupy open and closed positions, a collapsible bracket connecting the back section and support, means on the bracket tending to maintain the latter extended when moved to extended position,'a lever on the l back section operable to collapse the bracket against the action of said means, a spring on the back section tending to actuate the lever to collapse the bracket, and a cam on one of the side sections operable by movement of the side section to open position, to move the sections hingedly mounted on the back sec-- tion to occupy open and closed positions, a support for the frame, a hinged connection between the support and back section for supporting the frame for movement in a vertical plane, a collapsible bracket connected to the support and to the back section for ed to be fixed to an article of furniture, the said plate having an upwardly curvedslot, a hinge carried by the plate, the said slot being concentrically related to the pintle of the hinge, means connected with the hinge for supporting a book, a pin carried by said means and operating in said slot, and means cooperable with the plate and with the first said means for holding the latter in a relatively fixed position of tilted adjustment.
